关于PSASP谐波计算的问题

gpbaby199

我在进行谐波计算中的频率扫描，但是Fortran总是出现以下提示（由于上传不了图片，我就把那个提示码上来，大家见谅）
! B# E) t* q) y/ H
The variable (MARK(3)) has an undefined value.
8 @, F  X4 F: aError occurs at or near line 845 of _chrx_
8 X5 Q$ F. t) P0 X. s9 o: iCalled from or near line 535 of _eijop_
# X8 a) {& @! ?7 ?0 M/ C, PCalled from or near line 25 of _dwsubij_

Called from or near line 93 of _MAIN_
6 ?2 X- ?7 S5 g8 x% v
# R4 J/ k" k5 ^) l% ?/ U这上面的意思是有一个变量没有定义数据，但具体是哪一个我始终找不到，请问如何解决？
